Export Various Specifications Aisi 4130 Steels Mechanical Properties - China

The mechanical properties of AISI 4130 steels include:

Tensile strength (σb/MPa): ≥930

Yield point (σs/MPa): ≥785

Elongation (δ5/%): ≥12

Impact energy (Akv/J): ≥71

Impact toughness value (αkv/J/cm²): ≥88 - ①Austenitization time is not less than 0.5h, and tempering time is not less than 1h

②When selecting quenching medium for AISI 4130 steels, the influence of other parameters (shape, size and quenching temperature, etc.

) on performance and crack sensitivity should be considered.

Other quenching media (such as synthetic quenching agents) can also be used.

③In the standard parts industry, according to GB/T 3098.1-82, the tempering temperature range is 340~425°C.

The mechanical property values ​​in this case are quite different from the values ​​in the table.
